Bored with her clerical job, Kanako Oba, a 30-year-old divorcée, responds to an online ad: "Driver. Pay 300,000 yen. Entails some risk." Hired by a couple to be the driver of the getaway car in a cash heist, she soon finds herself entangled in a nightmarish world. She gets nabbed by a second gang of men and is about to be buried alive in a hole she herself has dug when an unidentified benefactor pays for her deliverance. She is taken to a diner named Canteen, a members-only eatery for hit men. Bombero, the proprietor, is a former hit man turned master chef, and Kanako is to work as his only waitress under the condition that if she disobeys him in the slightest she will be killed on the spot. Famous for its signature hamburgers in particular and its delectable gourmet menu in general, the shop is patronized by a parade of idiosyncratic assassins, among them Kid, who dresses up as a child and specializes in killing children; and Skin, whose face is crisscrossed by the tracks of his many wounds, said to have cumulatively required more than a thousand stitches. Bombero and his Canteen are under the protection of the Mafia, but then a suspicion arises that there may be a traitor or undercover agent in their midst in connection with a former mob boss's death . . . The work is at once deep and gloriously fun?the sort of novel you might expect film director Quentin Tarantino to immediately option.
